The future of green energy will be shaped by progressive decarbonization, digitalization and cross-sector integration. A survey of energy supply and industrial companies shows that significant changes are expected by 2025, including increased price sensitivity and challenges in standardization. The International Energy Agency forecasts a global boom in the solar industry by 2030, while the EU is relying on technologies such as wind and solar energy, heat pumps and electric cars to achieve climate neutrality by 2050. In the first half of 2023, developments in the renewable energy sector were mixed: despite the increase in installations, less renewable electricity was generated in the energy sector, while the heating sector recorded significant growth. Another challenge for 2023 is ensuring grid stability for the energy transition and preventing cyber attacks.
